DTCs P0641, P0651, P0697, and P06A3 are Type A DTCs.
Conditions for Clearing the DTC
DTCs P0641, P0651, P0697, and P06A3 are Type A DTCs.
Diagnostic Aids
P0641
The 5 V reference 1 circuit provides 5 V to the following sensors:
* B150 fuel tank pressure (FTP) sensor
* B17 barometric pressure (BARO) sensor, throttle inlet absolute pressure sensor
* B47B fuel rail pressure (FRP) sensor
* B1 A/C refrigerant pressure sensor
* All four B23 camshaft position sensors
P0651
The 5 V reference 2 circuit provides 5 V to the B26 crankshaft position sensor.
P0697
The 5 V reference 3 circuit provides 5 V to the following sensors:
* B74 manifold absolute pressure (MAP) sensor
* B107 accelerator pedal position sensor 2
P06A3
The 5 V reference 4 circuit provides 5 V to the following sensors:
* B106 throttle position sensor
* B107 accelerator pedal position sensor 1
瀚慖f the condition is intermittent, move the related harnesses and connectors with the engine operating. Monitor the scan tool 5 V Reference
Circuit Test Status parameters for the affected components. The Circuit Test Status parameter will change from OK or Not Run to Fault if
there is a condition with the circuit or a connection.
